and more devices need to be able to do wireless communication. With this background, Sky

microwave Co. Ltd. develops its MOD 9001D GSM/GPRS Modem. Users of this product can add

wireless communication capability easily to their own products, and then, develop many

applications.

The MOD 9001D GSM/GPRS Modem mostly fits the need of data transfer, with SMS data

communication, GPRS data navigation, Circuit Switch / Data Connectivity, TCP/IP protocol etc.

Because the easy setting up in SCM (Single Chip Micyoco), it is convenient for network data

communication. The MOD 9001D GSM/GPRS Modem with small size, which fits both embedded

application and external peripheral equipment. The AT command set and RS232 interface will

offer easy data connection without any extra circuit control.

Traditionally, the above applications use digital cellular, CDPD or other wire-line modem to

do communication, and these technologies are of the disadvantages of high communication

expense, limited communication range, dial before communications, etc. When we begin to

use MOD 9001D GSM/GPRS Modem, all these problems disappeared.
